CAR-HEATER.

SPECIFICATION forming part of Letters Patent No. 37'l,931,dated February14, 1888.

Application filed April 18, 1887. Serial No. 235,213. (No model.) v

the boiler can be utilized for extinguishing the,

iire in the heater in case of an accident tothe train or the carupsetting or assuming an abnormal position.

Our invention consists to this end of the irnprovements in theconstruction of the heater, as w1ll be hereinafter fully set forth, andpointed out in the claims.

In the accompanying drawings, Figure lv represents a sectional elevationof our improved car-heater and one end of a railwayca r. Fig. 2 is a topplan View of the heater. Fig. 3 is a cross-section in line x as, Fig. 1.Fig. 4 is asectional side elevation of the ratchet and pawl and hanginglever. Fig. 5 is a` perspective view of the locking-pawl.

Like letters of reference refer to like parts in the several figures.

A represents the firepot of our improved car-heater; A', the ash-pit;A2, the flame-passage, arranged above the fire-pot and communicatingwith the chimney or smoke-pipe A3. The latter extends through a sleevea, secured in an opening formed in the roof of the car.

B represents an annular water-chamber surrounding the fire-pot and theflame-passage A2, and provided with a suitable feed-pipe, b, whereby theWater is introduced into theboiler from a tank arranged in the carrorfromany other source of supply.

b represents the radiating-pipes through which the hot water from theheater is circulated through the car. The dame-passage A2 is formed by acylinder, C, which extends through an opening, c, formed in the top ofthe water-chamber B and rests with its lower edge upon the top of thefire-pot, forming a continuation of the fire-pot and also the inner wallof the water-chamber. The top of the -fire-pot is provided with anannular space or or secured to the top lof the cylinder Gand extendingoutwardlyover thetop of the water chamber. The plate G is provided inits upper side with a horizontal shaft, g,which is journaled in bearingsg', secured to the plate G.

H H represent liangedpulley's secured to the ends of the shaft g, and hh are chains or cables fastened at one end to the pulleys H and at theiropposite end to a ring or projection, h', secured to the outer side ofthe boiler or water-chamber B. The shaft g is provided at one of itsends with a crank, t'.

J J represent spiral springs interposed between the plate G and the topof the waterchamber B. The springs J are held inY place by vertical rodsj, which are secured to the top of the chamber B and extend throughopenings formed in the plate G.

K represents a ratchet-wheel secured to the shaft g, and k a pawlpivoted to an arm, lc', secured to the plate G and engaging with theteeth of the ratchet-wheel.

L represents ahanging lever mounted loosely on the shaft g, so as toswing thereon.I The lever L is provided with a short arm, Z, whichengages against a V- shaped projection or lug, m, formed on the pawl k,and a long arm, Z', which hangs in a vertical position from the shaft g,and is provided at its lower end with a weight, n.

Upon turning the shaft g by means of the crank the cables or chains harewound upon the pulleys H and the springs J are compressed between theplate G and the top of the chamber B. The cylinder C is also forced downupon the fire-pot, with its lower edge seated 'in the recess d. againstthe asbestus packing e.

rIhe parts are now in posit-ion for use, and are held in place by thepawl 7c engaging the ratchet-wheel K.

Upon the car assuming an' abnormal position in case of anv accident tothe train the upsetting or tilting of the car will cause the Air issupplied to the tire-pot through a suitable damper formed in the doorleading to the ash-pit, aud the fuel is supplied through an openingAformed in the top of the cylinder C, which is closed by a cover, o.

Our improved car-heater is very simple in construction, it occupies butlittle space, and forms a safe and reliable means for extinguishing thefire in case of an accident.

Te claim as our inventionl. In a car-heater, the combination, with thetire-pot A and a water-chamber, B, surrounding the fire-pot, of anadjustable cylinder, C, arranged above the fire-pot and forming theinner wall of the water-chamber and the dame` passage, substantially asset forth.

2. In a car-heater, the combination, with the lire-pot A, having arecess, d, around its upper edge and provided with a suitable packing,e, and a water-chamber, B, surrounding said nre-pot and provided at itstop with an opening, c, and stufting-boxf, of a cylinder, C, extendingthrough the stuffing-box and resting with its lower end in the recess dagainst the packing e, so as to form the inner wall of the water-chamberand the-flame-passage for the fire-pot, substantially as set forth.

3. In a car-heater, the combination,with the fire-pot A and chamber B,surrounding the tire-pot, of a cylinder C, extending through the chamberB and resting upon the upper edge of the tire-pot, a plate, G, securedto the top of the cylinder C, a shaft, g, journaled in bearings securedto the plate G, pulleys H, mounted on said shaft, and cables h, securedto the pulleys H and to the wall of the chamber B, substantially as setforth.

4. In a car-heater, the combination,with the lire-pot A and awater-chamber, B, surrounding the fire-pot, of a cylinder, C, extendingthrough the water-chamber and resting upon the upper edge of thefire-pot, a plate, G, secured to the top of the cylinder() and providedwith drums H, cables h, and ratchet mechanism K 7c, whereby the cylinderC is held in place upon the fire-pot, and springs J, interposed betweenthe plate G and the top of the chamber B and adapted to raise thecylinder C when the ratchet mechanism Kk is released, substantially asset forth.

5. In a car-heater, the combination,with the fire-pot A and awater-chamber, B, surrounding the fire-pot, of a cylinder, C, extendingthrough the chamber B and resting upon the upper edge of the fire-pot, aplate, G, secured to the top of the cylinder C, a shaft, g, journaled inbearings secured to said plate and provided with pulleys H, and cablesh, connecting said pulleys with the wall of the heater, a ratchet-wheel,K, secured to the shaft g, a pawl, k, engaging with the ratchet-wheel,and a hanging lever, L, pivoted to the shaft g and adapted to releasethe pawl k from the ratchetwheel K, substantially as set forth.
